RESUMO
Objective:To investigate the clinical efficacy of percutaneous endoscopic lumbar discectomy (PELD) with the aid of neurophysiological monitoring under general anesthesia.Methods:From August 2016 to October 2019, 58 patients underwent PELD under general anesthesia were selected in our hospital; 30 were via transformational approach and 28 were via interlaminar approach. The whole operative procedures were performed under continuous monitoring of spontaneous electromyography (SEMG), and the peak value, waveform and motor unit of SEMG at the surgical side were observed. The clinical outcomes were evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI).Results:PELD was successfully performed in all 58 patients. Abnormal SEMG reactions were recorded in 8 patients (13.8%), manifested as clustered or frequent high amplitude action potentials; 5 patients (16.7%, 5/30) were via transformational approach and 3 (10.7%, 3/28) were via interlaminar approach. Two patients relapsed at 3 and 6 weeks after surgery, respectively; one was treated with PELD again and the other one was treated with lumbar fusion and instrument fixation. The pain at the lumbago and leg was alleviated obviously after surgery in the 56 patients; the VAS scores were 7.43±1.32, 2.55±0.87 and 1.59±0.87 before surgery, and 3 d and 3 months after surgery, respectively, with significant differences ( P<0.05); the mean ODI before surgery and 3 months after surgery were 67.36±7.13 and 12.39±5.48, respectively, with significant difference ( P <0.05). Conclusion:PELD with the aid of neurophysiological monitoring under general anesthesia is safe and reliable, which can achieve good clinical efficacy.
RESUMO
Objective To investigate the curative effect of damage control theory in treating severe polytrauma patients combined with bone and joint injury. Methods A retrospective study was done on data including complication, death rate, fracture healing and joint function recovery of 63 patients with severe polytrauma combined with bone and joint injury( average ISS ≥27 points) admitted to our hospital from January 2006 to June 2009. Results Of all the patients, 57 shock patients were cured,three died of hemorrhagic shock within two hours after admission and one patient died of severe traumatic brain injury 11 hours after admission. One patient died of ARDS at 24 hours postoperatively and one died of multiple organ failure at day 6 after injury. Fracture healing was achieved in 52 patients, with satisfactory recovery of the limb function. Amputation was performed in two patients and three patients had mild claudication and pain walking. Conclusion Damage control strategy has great clinical significance in guidance of treatment of severe polytrauma combined with bone and joint injury.
